2nd International Conference on Computational and Experimental Science and Engineering (ICCESEN) -- OCT 14-19, 2015 -- Kemer, TURKEY ; WOS: 000384810700107 ; The class of generalized linear models is an extension of traditional linear models that allows the mean of the response variable to be linearly dependent on the explanatory variables through a link function. Generalized linear models allow the probability distribution of the response variable to be a member of an exponential family of distributions. The exponential family of distributions include many common discrete and continuous distributions such as normal, binomial, multinomial, negative binomial, Poisson, gamma, inverse Gaussian, etc. Also link functions can be built as identity, logit, probit, power, log, and complementary log-log link functions. In this study, supply, transformation and consumption, imports and exports of solid fuels, oil, gas, electricity, and renewable energy annual data of European Union countries between 2005 and 2013 years are investigated by using generalized linear models. In this case, the response variable is taken as annual complete energy balances of European Union countries as a continuous variable having positive values, and the distribution of the response variable comes from the gamma distribution with log-link function.

This paper examines economic and Information and Communication Technology (ICT) development influence on recently increasing Internet purchases by individuals for European Union member states. After a growing trend for Internet purchases in EU27 was noticed, all possible regression analysis was applied using nine independent variables in 2011. Finally, two linear regression models were studied in detail. Conducted simple linear regression analysis confirmed the research hypothesis that the Internet purchases in analyzed EU countries is positively correlated with statistically significant variable Gross Domestic Product per capita (GDPpc). Also, analyzed multiple linear regression model with four regressors, showing ICT development level, indicates that ICT development is crucial for explaining the Internet purchases by individuals, confirming the research hypothesis.

The following article is a recent bibliographic review of supplementary healthcare policies in Brazil and EU. The main focus is analyzing healthcare policies for the private sector in Brazil, within the context of Brazil's Unified National Health System (SUS), with the profile of the private sector in European Union countries, which have long had public systems integrated with social security. Our work is based on research conducted in the second decade of the 21st century. It is our understanding that comparing positions and progress made by the private sector, the growth of private and copayment health insurance and consequently the shrinking of public healthcare systems allows us to better understand the reach and meaning of those changes. We will initially analyze healthcare policies of Europe's private sector. Then we will discuss the supplementary healthcare system in Brazil, which is the main goal of this paper. Finally, we will compare cases according to progress and delays in private and public healthcare systems.

The process of demographic changes in European countries is characterized by greater and greater ageing of the population, as a result of the decline in the rate of natural increase and the rise in life expectancy. Europeans have less and less children, they live longer and face the problems how to ensure a safe old age. Noticed trends of change will be intensified till the middle of the new millennium (2050), when the following situation is expected: the decline in the number of children (0-14 years) for almost 20% and the active-working population (15-64), while there will be more "old persons" (65-79) for more than 44%, and "the oldest" persons (80 or more) for even 180%. Ageing of the population characterizes all regions, but is specially pronounced in the countries in the south and countries in transition. Faced with the challenges of the disturbances in the demographic structure, the members of the European Union (25) developed an entire spectrum of measures and activities to prevent the negative social-economic consequences. Creation of "the policy of ageing" at the Union level develops within the co-ordination (OMC) of the process of modernization of the social security system (old-age pension insurance, health insurance, social and child protection); it also implies the creation of conditions for "the active old age" (increase in employment and staying as long as possible on the job market), the development of "the new forms of solidarity" between generations (as a consequence of the increase of the coefficient of dependency between active working and supported population), preventing poverty and social exclusion, etc. Strategic documents, directions and national action-plans determined the concrete measures needed to face the demographic challenges.

Tourism is one of the most rapidly blossoming sectors of economy and its economic and social signi fi cance is expressed both in numbers (share in GNP, employment) and in a range of as important uncountable characteristics like expansion of a region, more intense development, building the spirit of local communities, actions preventing social exclusion or education of future generations for state progress. A number of countries, provinces and regions have achieved well- rounded social and economic growth by developing tourist economies and a range of necessary supporting measures, including complementary infrastructure, active and well-educated society by organising adequate living standards and ful fi lling basic social requirements, etc. It is therefore important to determine factors that improve competitiveness of tourism to maximum extent. The objective of this paper is to evaluate dependences between competitiveness of the European Union member states and selected factors determining competitiveness of tourism in these states. A set of factors determining competitiveness of tourism is introduced, that is, capacity of tourist accommodation establishments, arrivals at tourist accommodation establishments, average expenditure of tourism trips (1 night or over) – domestic trips, average expenditure of tourism trips (1 night or over) – outbound trips, tourism domestic trips (1 night or over), tourism outbound trips (1 night or over) and their impact on levels of competitiveness is determined. Considerable geographical variation of availability of accommodation establishments in the European Union member states and high, statistically signi fi cance correlations between availability of accommodation establishments and numbers of tourists arriving in a given states and between competitiveness of the EU states and tourism expenditure are identi fi ed.

European Union (EU) due to several challenges that exist nowadays has changed its Energy Policy. In order tofulfill international commitments concerning greenhouse gas emission and to assure safety in supply and stableprices, EU has been a leader in renewable energy. In many EU countries solar energy is a possible and veryviable option. Together with wind energy, photovoltaic energy is the new support core of a low carbon EUeconomy in what concerns electricity production. In this work clusters of countries were generated based on theenergy produced by PV systems and the share of energy from PV systems in the total electricity produced byrenewable sources. This work also analyzed the production of energy from the photovoltaic sector in EU andcompared it with the existing potential for this type of energy. Roughly half of the EU countries are producingenergy within the limits of what is expected, considering the irradiation on optimally inclined plane. Howeversome of them could improve the ratio between energy production and installed power. Considering the leadercountries in energy production from photovoltaic, Czech Republic and Spain are the countries that exceed whatit is expected. ; info:eu-repo/semantics/publishedVersion

In the European Union (EU), as a global economic community, there are countries with very different levels of economic development. Therefore, it takes place unevenly – some countries develop intensively, but with significant changes in it, others – stably, without significant changes, but not intensively, etc. In such a situation, it is important to determine adequately the current state of economic development. It is an integral quantity that combines both development changes and intensity. These two components of development form two of its partial indicators. Combined into one size, they comprehensively reflect the current situation of the country's economic development. Development refers to a process, so it must be assessed not on the basis of the state at the end of the period under consideration, but on the whole of this period. The presentation of development in the sense of recent years does not reflect the overall development process, based on the economic development of countries 2018–2022. Their ranks are determined by the results of the comprehensive assessment. Since they do not adequately reflect the current situation, the countries were combined into homogeneous groups, where countries with close values of the economic development indicator were located. This allows to highlight the economic development trends of EU countries.

The study intends to analyze how the shift to inspiring leadership in EU modern organizations reflects in the preferred leadership among employees from post-soviet Baltic countries: Lithuania, Latvia and Estonia. The main research question investigates employees' perception of an ideal leader in developing EU countries. This perception is important for the employees' work performance and sustainable economic growth. The study intends to compare Lithuanian, Latvian and Estonian employees' preferences for leader's traditional roles (task-oriented behavior and relations-oriented behavior) and modern "more emotional and inspiring" views (charisma and social responsibility). 221 employees participated in the cross-sectional quantitative survey with self-administered internet based questionnaires. 124 Lithuanians, 40 Latvians, 57 Estonians filled in the Hierarchical Taxonomy of Leadership Behaviors (Yukl, 2012), Transformational Leadership Inventory (Podsakoff et al., 1996) and a scale from Servant Leadership Questionnaire (Barbuto, Wheeler, 2006) was used. Results of this study suggest that charisma is the most preferred characteristic of a leader. Relations-oriented behavior is also a significant factor in predicting an ideal leadership. Employees do not perceive task-oriented behavior and leader's social responsibility as essential dimensions for an ideal leadership. Some significant differences in leadership preferences are revealed among countries. The study is based on under-estimated follower-centric perspective and examines interactive predictive value of different leadership dimensions to employees' preferences. Data reveals that the shift to inspiring leadership have already occurred in the perception of employees from post-soviet Baltic countries. The comparison of three Baltic countries gives the insight about the challenges for management in still developing EU members ; Psichologijos katedra ; Vytauto Didžiojo universitetas

Energy efficiency is one of the most effective methods of fighting climate change, achieving supply security and succeeding in resource effectiveness. For this reason, European Union (EU) countries follow mutual energy policies related to energy efficiency, with directives of the European Commission. This study used the Malmquist Total Factor Productivity Index to determine the extent to which 28 EU countries used energy efficiently in the output (GDP) production process in the period of 2005-2017. The results of the analysis indicated that the energy efficiency of EU-28 countries increased by an average of 1.1% for the period under review, and that the increases in efficiency varied between countries. Also, energy efficiency decreased only in Poland throughout the studied period. Although the Union has a common energy policy, it is thought that there are two main reasons for the energy efficiency differences in the member countries of the Union. The first of these is the energy structures of the countries, while the second is the energy policies of the countries that are shaped by their own internal dynamics.

This introductory essay briefly summarizes the 11 empirical studies of price setting and price adjustment that are included in this special issue. The studies, which use data from several European countries, were conducted as part of the European Central Bank's Inflation Persistence Network.

In this paper the valuation of macroeconomic factors influencing the Lithuanian direct investment into European Union was conducted. The problem of this paper is the different chosen macroeconomic factors influencing foreign direct investment. The object of this paper is Lithuanian direct investment. The methods of this paper include: comparative literature analysis, correlation regression analysis, paired regression analysis. After conducting a research of dependency of Lithuanian direct investment to EU countries from price changes, government sector income, gross domestic product, inflation, jobless rate results, it is found that gross domestic product and government sector income have the most influence on the changes of Lithuanian direct investment.

Economic development has resulted in structural transformation towards economies based on services, which has raised some concerns about the limited opportunities for sustaining productivity growth. The aim of this paper is to examine total factor productivity (TFP) growth in the service sector in comparison with total industries and the manufacturing sector, as well as within the service sector. The study is based on the data from the EU-KLEMS database (2017), and it covers the years 1995-2015. It refers to EU countries, making it possible to carry out a comparative analysis between countries, in particular between the 'old' and 'new' member states. The study demonstrates that productivity growth in services was significantly lower than in manufacturing, but compared with total industries, the disparity was not significant. Productivity growth was usually higher in the 'new' EU countries than in the 'old' ones, except for information and communications services, which, on the whole, were the main driving force behind the productivity growth in services.

The aim of this paper is to study the relation between banks' ownership structure and their risk-taking behavior. Additionally, we examine the impact of banking regulation on banks' approach to taking risk. The empirical analysis considers a sample of listed banks from EU countries over the period of 2011 to 2016. We found that the structure of the board of directors can influence bank risk behavior but not the ownership concentration. No significant relation was found between the influence of the regulatory environment and bank risk, i.e., stricter regulation has no effect on risk taking by banks. ; info:eu-repo/semantics/publishedVersion
